Description

Technical Field

[0001] The invention belongs to the technical field of sand mills, in particular to a vertical dual-power sand mill with a recycling function. Background Art

[0002] A sand mill is a horizontal wet continuous ultrafine particle disperser. The raw materials are fed into the grinding barrel, which is then filled with an appropriate amount of grinding media, such as glass beads. The motor then drives the dispersing blades (or pins) to rotate at high speed, giving the grinding media sufficient kinetic energy to collide with the dispersed material particles to generate shear force, achieving the dispersion effect. The dispersed material is then separated from the grinding media through a screen and discharged, resulting in uniform and excellent material quality. Continuous production is possible, thus improving quality and reducing costs. It is applicable to industries such as paint, ink, medicine, food, cosmetics, and pesticides.

[0003] The main structure of the current sand mill includes a frame, a grinding barrel, a machine spindle and a motor; the grinding barrel is arranged on the frame, and the grinding barrel has a rotor assembly for grinding materials.

[0004] When the sand mill grinds the material to a certain particle size, the material needs to be discharged. Currently, during the discharge process, the material is often discharged together with some grinding media - zirconium beads. However, due to the small size of the zirconium beads themselves, it is difficult to collect them in a centralized manner, which affects the normal grinding of the sand mill.

[0005] To this end, the present invention provides a vertical dual-power sand mill with a recovery function. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the vertical dual-power sand mill with recycling function described in the present invention comprises a sand mill body, a sand mill cylinder is installed inside the sand mill body, a grinding cavity is opened inside the sand mill cylinder, a main shaft is provided for rotation inside the sand mill cylinder, the end of the main shaft is connected to the output end of the motor, an inner cylinder is fixedly installed on the outer surface of the main shaft, and rod pins designed in an array are fixedly installed on the outer circumference of the inner cylinder, a feed pipe is installed at the bottom of the sand mill cylinder, and a separator is provided for rotation inside the sand mill cylinder. A separation shaft is installed inside the separator, and a discharge through hole is opened inside the separation shaft; when working, the material to be ground is passed into the grinding chamber inside the sand mill cylinder through the feed pipe, and the motor is controlled to drive the main shaft to rotate, and the main shaft drives the rod pins with an array design on its outer surface to rotate synchronously. Under the high-speed rotation of the main shaft and multiple rod pins, the rod pins can exert strong shearing, impact and friction on the material, and gradually grind the material; at the same time, the separator is driven independently to make the separator rotate at high speed, thereby realizing independent control of grinding and separation, avoiding the speed coupling problem of traditional single power system.

[0008] Preferably, a mounting bracket is installed on the upper side of the side wall of the sand mill body, and a separation motor is fixedly installed inside the mounting bracket, and a pulley 1 is installed on the output end of the separation motor, and a pulley 2 is installed on the upper end of the separator, and the pulley 1 and the pulley 2 are connected by a belt; during operation, when the main shaft drives the rod pin to rotate through the inner cylinder, and when it is necessary to control the rotation of the separator, the separation motor is controlled to operate so that the output end of the separation motor drives the pulley 1 to rotate, and the pulley 1 drives the pulley 2 to rotate through the belt, and the pulley 2 can drive the separator to rotate. Such a design can conveniently adjust the speed of the separator to adapt to different material viscosities, ensure efficient centrifugal sedimentation of the zirconium beads in the separation area, and reduce the risk of entering the through hole.

[0010] Preferably, an inner tube is installed inside the bead filter, the top end of the inner tube passes through the inside of the discharge elbow, and a discharge trough is provided at the bottom of the inner tube, and the diameter of the discharge trough is smaller than the diameter of the zirconium beads; during operation, when the material is adsorbed from the discharge elbow to the inside of the bead filter, the material and part of the zirconium beads will enter the inside of the inner tube, and the material will gradually move along the top of the inner tube to the bottom of the inner tube, and be discharged from the inside of the discharge trough. Since the diameter of the discharge trough is smaller than the diameter of the zirconium beads, the zirconium beads will remain inside the inner tube, which can achieve the separation of the material and the zirconium beads, and is conducive to the subsequent centralized treatment of the zirconium beads.

[0011] Preferably, a solvent tank is installed on the upper side of the side wall of the sand mill body, and the solvent tank is used to clean the zirconium beads inside the inner tube. A transmission unit is provided on the outside of the bead filter, and the transmission unit is used to transmit the zirconium beads collected inside the inner tube.

[0013] Preferably, a spiral pipe is provided inside the solvent tank, the top of the spiral pipe is connected to the end of the transmission pipe, and a delivery pipe is installed on the outside of the solvent tank, one end of the delivery pipe passes through the inside of the spiral pipe, and the other end is connected to an external storage tank, a cleaning solvent is provided inside the storage tank, and a recovery unit is provided at the bottom of the spiral pipe, and the recovery unit is used to recover the cleaned zirconium beads; during operation, when the zirconium beads inside the inner tube are gradually adsorbed into the inside of the solvent tank, the cleaning solvent is first passed into the inside of the spiral pipe through the delivery pipe, and the zirconium beads passing through the transmission pipe will fall into from the top of the spiral pipe and gradually move along the spiral path of the spiral pipe to the recovery unit at its bottom, thereby realizing the automatic cleaning function of the zirconium beads. The spiral pipe is designed, and the cleaning solvent is provided inside the spiral pipe, which prolongs the delivery time of the zirconium beads and improves the cleaning effect of the zirconium beads.

[0014] Preferably, the recovery unit includes a recovery frame, which is installed at the bottom of the spiral pipe. Three layers of vibrating screens are installed inside the recovery frame, and sieve holes are opened on the surface of each layer of vibrating screen. The diameter of the sieve holes of the vibrating screen decreases from top to bottom, and the side wall of the vibrating screen is connected to the output end of the vibration motor; when working, when the cleaned zirconium beads fall along the spiral pipe to the inside of the recovery frame below, the zirconium beads will first fall on the surface of the topmost vibrating screen, and under the continuous vibration of the vibrating screen, the diameter of the sieve holes of the three layers of vibrating screen gradually decreases from top to bottom. Therefore, the diameter of some zirconium beads with more serious wear becomes smaller, so they will first fall along the topmost vibrating screen to the middle vibrating screen, and some smaller fragments will continue to fall along the middle vibrating screen to the bottom vibrating screen. In this way, the damaged zirconium beads can be screened, and the problem of some excessively worn zirconium beads flowing back into the grinding chamber and affecting the normal grinding of the material can be avoided, and the excessively worn zirconium beads can be collected.

[0015] Preferably, the three layers of vibrating screens are all of inclined design, and the side walls of the recovery frame are provided with three collecting ports, which are located on the side walls of the vibrating screen. During operation, since the vibrating screen is of inclined design, the worn or unworn zirconium beads on the surface of each layer of the vibrating screen will slide along its inclined surface to the collecting port and be collected through the collecting port. The vibration spring is designed to improve the vibration effect of the vibrating screen, and the cleaning solvent will gradually fall to the bottom of the recovery frame, which is convenient for subsequent collection and reuse.

[0016] Preferably, the side walls of each layer of the vibrating screen are installed with vibration springs, and the bottom of the recovery frame is provided with a collecting trough.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 12As shown, a vertical dual-power sand mill with a recycling function described in an embodiment of the present invention includes a sand mill body 1, a sand mill cylinder 2 is installed inside the sand mill body 1, a grinding cavity is opened in the sand mill cylinder 2, a main shaft 3 is rotatably provided inside the sand mill cylinder 2, the end of the main shaft 3 is connected to the output end of the motor, an inner cylinder 302 is fixedly installed on the outer surface of the main shaft 3, and rod pins 301 designed in an array are fixedly installed on the outer circumference of the inner cylinder 302, a feed pipe 4 is installed at the bottom of the sand mill cylinder 2, a separator 201 is rotatably provided inside the sand mill cylinder 2, a separation shaft 202 is installed inside the separator 201, a discharge through hole 5 is opened inside the separation shaft 202, and a bead filter 9 is provided on the side wall of the sand mill body 1, and the bead filter 9 is used to collect zirconium beads; During operation, the material to be ground is introduced into the grinding chamber inside the sand mill cylinder 2 through the feed pipe 4, and the motor is controlled to drive the main shaft 3 to rotate. The main shaft 3 drives the rod pins 301 designed in an array on its outer circumference to rotate synchronously. Under the high-speed rotation of the main shaft 3 and the multiple rod pins 301, the rod pins 301 can exert strong shearing, impact and friction effects on the material, and gradually grind the material; at the same time, the separator 201 is independently driven to rotate at high speed, thereby achieving independent control of grinding and separation, avoiding the speed coupling problem of traditional single-power systems; When the separator 201 rotates at high speed, under the action of centrifugal force, the grinding medium - zirconium beads will be thrown into the interior of the grinding chamber when they come into contact with the separator 201, and when the separator 201 rotates at high speed, it will drive the separation shaft 202 to rotate synchronously, so some of the smaller and lighter material solutions after grinding will be discharged through the opening in the middle of the separator 201, realizing the function of automatically recovering the material. After that, the filter bead filter 9 can collect some of the zirconium beads sucked into the interior of the separator 201, thereby facilitating the subsequent recycling and reuse of the zirconium beads.

[0024] A mounting frame 6 is installed on the upper side of the side wall of the sand mill body 1, and a separation motor 601 is fixedly installed inside the mounting frame 6. A pulley 1 7 is installed at the output end of the separation motor 601, and a pulley 2 8 is installed at the upper end of the separator 201. The pulley 1 7 and the pulley 2 8 are connected by a belt. During operation, when the main shaft 3 drives the rod pin 301 to rotate through the inner cylinder 302, and when it is necessary to control the rotation of the separator 201, the separation motor 601 is controlled to operate, so that the output end of the separation motor 601 drives the pulley 1 7 to rotate, and the pulley 1 7 drives the pulley 2 8 to rotate through the belt, and the pulley 2 8 can drive the separator 201 to rotate. This design can easily adjust the rotation speed of the separator 201 to adapt to different material viscosities.

[0025] A discharge elbow 602 is installed on the side wall of the mounting frame 6. The bead filter 9 is connected to the side of the mounting frame 6 through a bracket. One end of the discharge elbow 602 passes through the discharge through-hole 5, and the other end passes through the bead filter 9. A circulating adsorption pump 10 is installed at the bottom of the bead filter 9. The adsorption end of the circulating adsorption pump 10 passes through the interior of the bead filter 9. During operation, when the material is ground normally inside the sand mill cylinder 2, the circulating adsorption pump 10 is controlled to operate at the same time, so that the circulating adsorption pump 10 generates a certain adsorption force, and the suction force generated by the circulating adsorption pump 10 can further adsorb the material entering the separator 201 and the discharge through hole 5 into the discharge elbow 602, and adsorb it into the bead filter 9 through the discharge elbow 602. After that, the material will be discharged from the bottom of the bead filter 9, and the zirconium beads will remain inside the bead filter 9, which is convenient for the subsequent recycling of the zirconium beads.

[0026] An inner tube 11 is installed inside the bead filter 9, and the top end of the inner tube 11 passes through the inside of the discharge elbow 602. A discharge trough 12 is provided at the bottom of the inner tube 11, and the diameter of the discharge trough 12 is smaller than the diameter of the zirconium beads. During operation, when the material is adsorbed from the discharge elbow 602 to the inside of the bead filter 9, the material and part of the zirconium beads will enter the inside of the inner tube 11, and the material will gradually move along the top of the inner tube 11 to the bottom of the inner tube 11, and be discharged from the inside of the discharge trough 12. Since the diameter of the discharge trough 12 is smaller than the diameter of the zirconium beads, the zirconium beads will remain inside the inner tube 11, thereby achieving the separation of the material and the zirconium beads, and facilitating the subsequent centralized treatment of the zirconium beads.

[0027] A solvent tank 13 is installed on the upper side of the side wall of the sand mill body 1, and the solvent tank 13 is used to clean the zirconium beads inside the inner tube 11. A transmission unit is provided on the outside of the bead filter 9, and the transmission unit is used to transmit the zirconium beads collected inside the inner tube 11; the transmission unit includes a transmission pipe 14, one end of the transmission pipe 14 passes through the inside of the inner tube 11, and the other end passes through the inside of the solvent tank 13, and the end of the transmission pipe 14 near the inner tube 11 is provided with a blocking door 141, and the interior of the transmission pipe 14 is installed with a suction pump body 15; when working, when the interior of the inner tube 11 stores a certain amount of zirconium beads, the transmission unit 14 includes a transmission pipe 14, and a transmission pipe ... When a fixed amount of zirconium beads is added, the rotation of the main shaft 3 inside the grinding chamber is stopped first, and then the suction of the circulating adsorption pump 10 is stopped. Then, the suction pump body 15 is controlled to operate, so that the suction pump body 15 generates a suction force in the transmission tube 14, and drives the blocking flap 141 to rotate, and the end of the transmission tube 14 close to the inner tube 11 is opened. After that, the zirconium beads inside the inner tube 11 will be gradually adsorbed into the solvent tank 13, and the zirconium beads can be cleaned by the solvent inside the solvent tank 13, and the material residue on the surface of the zirconium beads can be cleaned, so as to avoid the reduction of the grinding efficiency of the zirconium beads during subsequent use, and the problem of material contamination; It should be noted that the blocking flap gate 141 is a check valve with the function of preventing backflow. When it is not subjected to the suction force of the suction pump body 15, the blocking flap gate 141 is used to block the end of the transmission pipe 14. When it is subjected to the suction force of the suction pump body 15, the blocking flap gate 141 will rotate to a certain amplitude and open the end of the transmission pipe 14.

[0028] The solvent tank 13 is provided with a spiral pipe 16 inside, the top of the spiral pipe 16 is connected to the end of the transmission pipe 14, and a delivery pipe 17 is installed outside the solvent tank 13. One end of the delivery pipe 17 passes through the interior of the spiral pipe 16, and the other end is connected to an external storage tank. The storage tank is provided with a cleaning solvent. The bottom of the spiral pipe 16 is provided with a recovery unit, which is used to recover the cleaned zirconium beads. During operation, when the zirconium beads inside the inner tube 11 are gradually adsorbed into the solvent tank 13, the cleaning solvent is first passed into the spiral pipe 16 through the delivery pipe 17, and the zirconium beads passing through the transmission pipe 14 will fall from the top of the spiral pipe 16 and gradually move along the spiral path of the spiral pipe 16 to the recovery unit at its bottom, thereby realizing the automatic cleaning function of the zirconium beads. The spiral pipe 16 is designed, and a cleaning solvent is provided inside the spiral pipe 16, which extends the delivery time of the zirconium beads and improves the cleaning effect of the zirconium beads.

[0029] The recovery unit includes a recovery frame 18, which is installed at the bottom of the spiral pipe 16. Three layers of vibrating screens 19 are installed inside the recovery frame 18. The surface of each layer of vibrating screen 19 is provided with sieve holes 20. The diameter of the sieve holes 20 of the vibrating screen 19 decreases from top to bottom. The side wall of the vibrating screen 19 is connected to the output end of the vibration motor. During operation, when the cleaned zirconium beads fall along the spiral pipe 16 to the inside of the recovery frame 18 below, the zirconium beads will first fall on the surface of the topmost vibrating screen 19, and under the continuous vibration of the vibrating screen 19, the diameter of the screen holes 20 of the three-layer vibrating screen 19 gradually decreases from top to bottom. Therefore, the diameter of some zirconium beads with more serious wear becomes smaller, so they will first fall along the topmost vibrating screen 19 to the middle vibrating screen 19, and some smaller fragments will continue to fall along the middle vibrating screen 19 to the bottom vibrating screen 19. In this way, the damaged zirconium beads can be screened, and some excessively worn zirconium beads can be prevented from flowing back into the grinding chamber and affecting the normal grinding of the material, and the excessively worn zirconium beads can be collected.

[0030] The three layers of vibrating screens 19 are all inclined, and the side walls of the recovery frame 18 are provided with three collecting ports 21, which are located on the side walls of the vibrating screen 19; the side walls of each layer of the vibrating screen 19 are installed with vibration springs 22, and the bottom of the recovery frame 18 is provided with a collecting trough; During operation, since the vibrating screen 19 is designed to be inclined, the worn or unworn zirconium beads on the surface of each layer of the vibrating screen 19 will slide along its inclined surface to the collecting port 21 and be collected through the collecting port 21. The vibration spring 22 is designed to improve the vibration effect of the vibrating screen 19. At the same time, the cleaning solvent will gradually fall to the bottom of the recovery frame 18, which is convenient for subsequent collection and reuse.

[0031] During operation, the material to be ground is introduced into the grinding chamber inside the sand mill cylinder 2 through the feed pipe 4, and the motor is controlled to drive the main shaft 3 to rotate. The main shaft 3 drives the rod pins 301 designed in an array on its outer circumference to rotate synchronously. Under the high-speed rotation of the main shaft 3 and the multiple rod pins 301, the rod pins 301 can exert strong shearing, impact and friction effects on the material, and gradually grind the material; at the same time, the separator 201 is independently driven to rotate at high speed, thereby achieving independent control of grinding and separation, avoiding the speed coupling problem of traditional single-power systems; When the separator 201 rotates at high speed, under the action of centrifugal force, the grinding medium - zirconium beads will be thrown into the interior of the grinding chamber when they come into contact with the separator 201, and some of the smaller and lighter material solution after grinding will be discharged into the middle opening of the separator 201, realizing the function of automatically recovering the material; when the main shaft 3 drives the rod pin 301 to rotate through the inner cylinder 302, and when it is necessary to control the rotation of the separator 201, the separation motor 601 is controlled to operate at this time, so that the output end of the separation motor 601 drives the pulley 1 7 to rotate, and the pulley 1 7 drives the pulley 2 8 to rotate through the belt, and the pulley 2 8 can drive the separator 201 to rotate. Such a design can easily adjust the rotation speed of the separator 201 to adapt to different material viscosities; When the material is ground normally inside the sand mill cylinder 2, the circulation adsorption pump 10 is controlled to operate at the same time, so that the circulation adsorption pump 10 generates a certain adsorption force, and the suction force generated by the circulation adsorption pump 10 can further adsorb the material entering the separator 201 and the discharge through hole 5 into the discharge elbow 602, and adsorb it into the bead filter 9 through the discharge elbow 602. After that, the material will be discharged from the bottom of the bead filter 9, and the zirconium beads will remain in the bead filter 9, thereby facilitating the subsequent recycling of the zirconium beads; when the material is adsorbed from the discharge elbow 602 into the bead filter 9, the material and part of the zirconium beads will enter the interior of the inner tube 11, and the material will gradually move along the top of the inner tube 11 to the bottom of the inner tube 11, and be discharged from the inside of the discharge trough 12. Since the diameter of the discharge trough 12 is smaller than the diameter of the zirconium beads, the zirconium beads will remain in the inner tube 11, so that the material and the zirconium beads can be separated, and it is beneficial to the subsequent centralized treatment of the zirconium beads. When a certain amount of zirconium beads are stored in the inner tube 11, the main shaft 3 in the grinding chamber is stopped first, and then the suction of the circulating adsorption pump 10 is stopped. Then the suction pump body 15 is controlled to operate, so that the suction pump body 15 generates a suction force in the transmission tube 14, and drives the blocking flap 141 to rotate, and the end of the transmission tube 14 close to the inner tube 11 is opened. After that, the zirconium beads in the inner tube 11 will be gradually adsorbed into the solvent tank 13, and the zirconium beads can be cleaned by the solvent in the solvent tank 13, and the material residue on the surface of the zirconium beads can be cleaned to avoid subsequent use. The grinding efficiency of the zirconium beads decreases, and it may cause the problem of material contamination. When the zirconium beads inside the inner tube 11 are gradually adsorbed into the solvent tank 13, the cleaning solvent is first introduced into the spiral pipe 16 through the delivery pipe 17, and the zirconium beads passing through the delivery pipe 14 will fall from the top of the spiral pipe 16 and gradually move along the spiral path of the spiral pipe 16 to the recovery unit at the bottom thereof, thus realizing the automatic cleaning function of the zirconium beads. The spiral pipe 16 is designed, and the cleaning solvent is provided inside the spiral pipe 16, which prolongs the delivery time of the zirconium beads and improves the cleaning effect of the zirconium beads. When the cleaned zirconium beads fall along the spiral pipe 16 to the inside of the recovery frame 18 below, the zirconium beads will first fall on the surface of the uppermost vibrating screen 19, and under the continuous vibration of the vibrating screen 19, the diameter of the sieve holes 20 of the three-layer vibrating screen 19 gradually decreases from top to bottom. Therefore, the diameter of some zirconium beads with more serious wear becomes smaller, so they will first fall along the uppermost vibrating screen 19 to the middle vibrating screen 19, while some smaller fragments will continue to fall along the middle vibrating screen 19 to the bottom vibrating screen 19, so that the damaged zirconium beads can be cleaned. The beads are screened to avoid some over-worn zirconium beads from flowing back into the grinding chamber and affecting the normal grinding of the material, and the over-worn zirconium beads can be collected. Since the vibrating screen 19 is designed to be inclined, the worn or unworn zirconium beads on the surface of each layer of the vibrating screen 19 will slide along its inclined surface to the collecting port 21 and be collected through the collecting port 21. The vibration spring 22 is designed to improve the vibration effect of the vibrating screen 19. At the same time, the cleaning solvent will gradually fall to the bottom of the recovery frame 18, which is convenient for subsequent collection and reuse.
